Coherence bandwidth measurements in an indoor microcell at 62.4 GHz

Results of experiments made at 62.4 GHz in a long narrow corridor to measure the coherence bandwidth are presented. The correlation coefficients between envelopes separated in frequency are measured and expressed as functions of distance between terminals. They are found to be highly variable with the location of the terminals in the microcell. From these data the frequency correlation function is computed and used to calculate the coherence bandwidth. The coherence bandwidths for correlation levels of 0.5, 0.7, and 0.9 are given for 90% of the time
